ARMOR FOR PRISON-CELLS.

SPECIFICATION forming part of Letters Patent No. 271,633, dated February 6, 1863.

I y Applieationled May19,1882. (No model.) l v To all whom it may concern:

Be it known that I, PHILIP HERZOG', a. citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have made certain new and uselul Improvements in Armor for Prison- Cells, set forth in the annexed specification.

l This invention relates to the cells of prisons, `jails, and other places for the continement ot' prisoners, and arranged and constructed as hereinafter shown and as specifically claimed.

' In the drawings, Figure lis a cross-sectional view-7 Fig. 2 is a front view,'partiall v in see tion, and Fig. 3 is a horizontal sectional view, ot' a portion of the wall of a celliwith my improved armor attached thereto.

A is the sheet-metal wall of the cell, which may be of steel or vother metal, with thejoints between the plates covered by strips ein the ordinary manner. Cells made in this manner are secure under ordinary circumstances, but can be cut through by suitable instruments in the hands of persistent and skillful prisoners; and to guard against this, cells have been heretot'ore constructed with hardened steel bars riveted fast to the walls ofthe cells at intervals small enough to prevent the passage of a prisoner between them should the inner wall be cut through; and to still further protect the cells and provide an armor that cannot be cut through at the same time that the cell-wall is cut through, I construct a lattice-work of metal bars, B, ot' either hardened steel, carbonized iron, or 0theriile-proof metal, at asut'-A licientdistance away from the walls A of the cell to prevent both the bars and wall from being cut at the same time by the same implement. By this means the chances of escape are lessened 0ne-halt by increasing twofold the work necessary to cut through the cells.

The bars B may be connected to the cells in any suitable manner, either by their ends to the corners ofthe cells or by rivets b through each pair of bars where they cross each other, and then the same rivets continued on through the wall A, and riveted therein in countersunk holes on the inside, so that no projections occur on the inside ot' the cell. The rivets between the bars B and walls A are surrounded by metal tubes or gaskets77 U to hold the bars B out-from the walls the required distance. The cell-walls are greatly strengthened and stiffened by this means, so that thinner metal may be used for the walls to secure equal strength, and thus a saving in expense and weight secured.

. The bars Bl may be arranged to cross each other, as shown, or in diagonal or parallel lines.

One of the rows of rivets b may be utilized to hold one side ofthe strips a, as shown.

The bars B may be made of any suitable material; but I prefer them of ca'rbonized iron, as being cheaper and stronger than steel or other metal.

1. An armor for priscn-cells, consisting ot' metal bars B close enough to each other to prevent the passage ot' a person between them, and at a sufficient distance from the walls ot' the cells to prevent both of said walls and bars being cut at the same time byone instrument.

2. The walls A. in combination with bars B, rivets b, and gaskets C, substantially as and for lthe purpose set forth.

In testimony whereof I have hereunto setv my hand in the presence ot' two subscribing witnesses.

PHILIP HERZOG.
